As a result of going back to work just two months after Milan's birth, the "Whenever, Wherever" singer disclosed that getting back into her pre-baby shape was not easy, among other surprises of motherhood.

"I didn't expect babies to need so many diapers," exclaimed the 36-year-old mother during the NBC Summer Press Day in April, according to US Weekly. "Nobody told me they needed to be changed so often!"

Furthermore, "The Voice" mentor noted the high demands placed on women by the entertainment industry as well as society to get back into shape following the arrival of a baby.

"I mean, I guess our mothers and grandmothers weren't under the pressure that women of today are after delivering a baby," explained the singer. "My dad says that there's nothing better than a little meat on the bone! He likes my mom a little chubby. So she was never under pressure to get back to her old weight, and she never did, actually!"

However, the 36-year-old singer did not take an extended maternity leave and headed back to the television studio in March.

"It's different, I have a career, and that's the only part that's been a bit stressful because I knew that I'd have to come back here to do 'The Voice'," said Shakira. "I didn't have my four months maternity leave like every woman on earth has. So I'm not trying to complain, but it's been a process full of challenges in my life."

Shakira also noted that dancing during Zumba classes helped her get back into shape.
